I know it is usually easier to go from an acyl chloride to an aldehyde,
but is there a way to synthesize acyl chlorides from an aldehyde?
Edit:
Upon some textbook reading (Wiley: Organic Chemistry 11th Ed, Solomons), I realized that aldehydes could also be oxidized to carboxylic acids with chromic acid in aqueous acetone (the Jones Oxidation) and then you could react the carboxylic acid with thionyl chloride or phosphorus trichloride to yield the acyl chloride.
Another method was to convert the aldehyde into a cyanohydrin and through hydrolysis the -CN group could be then converted into $\ce{RCOOH}$. Then react $\ce{RCOOH}$ with $\ce{SOCl2}$ to get the acyl chloride.
